Abstract
Objective: During young adulthood (20-35) years of age, both biological function and physical performance reach their peak. The degeneration of muscle strength with aging is due to the overall decrease in muscle mass, especially the type II muscle fibres. And the lower extremity is more affected by aging than the upper extremity due to less use of lower limbs than upper limbs in daily activity. Thus, this study wanted to find out the quadriceps muscle strength among healthy individuals of different age groups. Methodology: A cross sectional Study was conducted on 120 healthy individuals. Subjects were selected based on the inclusion criteria. (I) Four equal sized groups, 20–25, 25–30, 30-35, 35-40 years of age, without any neurological and orthopaedic disorders Persons with diabetes/thyroid and lower limb injuries, with concurrent Musculoskeletal, Neurological, Cardiovascular disorders. Were excluded. Quadriceps muscle strength were assessed by using micro FET2 Dynamometer. Results: By Applying ANOVA significant difference was found in quadriceps strength among different age groups (p-value is < 00001.) Conclusion: This study concluded that quadriceps muscle strength varies among different age groups of healthy individuals.
